React app built with GPT Engineer? Let’s review it.
Expert code review for React apps built with GPT Engineer. We find GPT Engineer-specific bugs, fix React security issues, and optimize performance. From $19.
GPT Engineer issues we find in React projects
Problems specific to GPT Engineer's code generation patterns when building React apps.
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Missing error boundaries
A single component error crashes the entire application. No error boundaries or fallback UIs to gracefully handle failures.
React issues we check for
Common React problems that affect production readiness.
XSS via dangerouslySetInnerHTML
AI tools use dangerouslySetInnerHTML to render dynamic content without sanitization, allowing script injection.
Exposed environment variables
Sensitive keys placed in NEXT_PUBLIC_ or REACT_APP_ prefixed variables, making them visible in the browser bundle.
Unnecessary re-renders
Missing React.memo, useMemo, and useCallback cause components to re-render on every parent update, degrading performance.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.
